Fig. 1-3 illustrate an electronic atomizing device 100 in some embodiments of the present invention, the electronic atomizing device 100 being operable to atomize a liquid substrate to produce an aerosol that can be inhaled or inhaled by a user, which in this embodiment can be generally cylindrical. It is understood that in other embodiments, the electronic atomizing device 100 may have other shapes such as an elliptic cylinder, a flat cylinder, or a square cylinder. The liquid matrix may include tobacco tar or liquid medicine.

The electronic atomizing device 100 may include a housing 10, a control module 20 housed in the housing 10, a power source 30, a gas source 40, a liquid storage atomizing assembly 60, and a bracket assembly 70. The air source 40 is connected to a reservoir atomizing assembly 60 for providing a high velocity air stream, which may typically be an air pump. The control module 20 is electrically connected to the air source 40, and is configured to receive an instruction, where the instruction may be triggered by a user or automatically triggered when the electronic atomizing device 100 satisfies a certain condition, and the control module 20 controls the operation of the air source 40 according to the instruction. The power supply 30 is electrically connected to the control module 20 and the air source 40, respectively, and is used for providing electric energy to the control module 20 and the air source 40.

The liquid storage and atomization assembly 60 may be supported on the bracket assembly 70, and a liquid storage chamber 610 for storing a liquid matrix, an air flow channel 630 for atomizing the liquid matrix to generate liquid particles, and a liquid supply channel 620 communicating the liquid storage chamber 610 and the air flow channel 630 are formed in the liquid storage and atomization assembly 60. Further, the gas flow channel 630 is in communication with the gas source 40, and the liquid medium entering the gas flow channel 630 from the liquid supply channel 620 can be atomized by the high-speed gas flow flowing through the gas flow channel 630 to form fine liquid particles. One end of the housing 10 is provided with an air suction opening 14, which air suction opening 14 communicates with the air flow channel 630 for outputting atomized liquid particles for inhalation or inhalation by a user.

A vent pipe 80 may be further provided in the housing 10, and an inner wall surface of the vent pipe 80 defines an output passage 81, and the output passage 81 communicates the air flow passage 630 with the air suction port 14. Specifically, in the present embodiment, the output passage 81 extends in the longitudinal direction, the upper end of the output passage 81 communicates with the suction port 14, and the lower end of the output passage 81 communicates with the upper end of the airflow passage 630.

In particular, as shown in fig. 3-5, the reservoir atomization assembly 60 may include a reservoir assembly 61 and a nozzle 63 at least partially received in the reservoir assembly 61. An air flow channel 630 is formed within the nozzle 63, which may extend longitudinally through the nozzle 63. The air flow channel 630 may include an air supply channel 632 and an atomizing channel 631. The atomizing channel 631 communicates with the air source 40 via an air supply channel 632 and communicates with the reservoir chamber 610 via an air supply channel 620. The atomizing channel 631 forms an atomizing face 6313 adjacent to an end face of the air supply channel 632, and an atomizing port 6310 is also formed in the atomizing face 6313. The high-velocity air flow from the air supply channel 632 is ejected into the atomizing channel 631 via the atomizing port 6310 and flows at a high velocity in the atomizing channel 631, and the high-velocity air flow generates a negative pressure in the atomizing channel 631 and the liquid supply channel 620 by the Bernoulli equation, and the negative pressure is conducted to the liquid chamber 610 to suck the liquid medium in the liquid chamber 610 out to the atomizing channel 631, forming a liquid film on the atomizing surface 6313. As the liquid supply process continues, the liquid film moves to the edge of the hole wall of the atomization opening 6310 to meet the high-speed air flow, and is cut and atomized into fine liquid particles by the high-speed air flow, and the liquid particles are carried away from the atomization opening 6310 by the air flow and then are sprayed out along with the air flow to complete the atomization process. The atomization mode of the liquid matrix in the atomization channel 631 is a non-phase-change atomization mode, and the particle size distribution of liquid particles formed after atomization of the atomization channel 631 can reach the range of smd=30 μm. Where SMD = total volume of liquid particles/total surface area of liquid particles, represents the average particle size of the liquid particles.

The atomizing channel 631 includes an atomizing chamber 6311 with a bottom surface of the atomizing chamber 6311 forming an atomizing face 6313. The atomizing chamber 6311 may be a straight cylindrical passage with a wall surface perpendicular to the atomizing face 6313. In this embodiment, the atomizing chamber 6311 is a straight cylindrical channel, the atomizing surface 6313 is concentric with annular shape, and an inner wall surface of the atomizing surface 6313 defines the atomizing opening 6310. In other embodiments, the cross-section of the atomizing chamber 6311, atomizing face 6313, or atomizing port 6310 may be oval or rectangular, among other non-circular shapes.

The size and shape of the atomizing port 6310 and the atomizing chamber 6311 can influence the size of the negative pressure in the atomizing chamber 6311 and the particle size of the generated liquid particles, and can stabilize the flow rate. In some embodiments, the aperture of the atomizing port 6310, the aperture of the atomizing chamber 6311, and the length of the atomizing chamber 6311 may be sized as desired.

Specifically, the pore size of the atomizing port 6310 is related to the air flow rate (m/s) exiting from the atomizing port 6310, which can affect the particle size of the generated liquid particles. In some embodiments, the aperture of the atomizing port 6310 may range from 0.2mm to 0.4mm, preferably from 0.22mm to 0.35mm.

The aperture of the nebulization chamber 6311 affects the magnitude of the airflow velocity in the nebulization chamber 6311 and thus the magnitude of the negative pressure in the nebulization chamber 6311 and the supply channel 620. The negative pressure may draw liquid matrix from the liquid supply channel 620 to the nebulization chamber 6311. In some embodiments, the atomizing chamber 6311 may have a pore size in the range of 0.7mm to 1.3mm. The axial length of the atomizing chamber 6311 may be 0.8mm to 3.0mm. It will be appreciated that in other embodiments, the atomizing port 6310 or the atomizing chamber 6311 may also have a non-circular cross-section; when the atomizing port 6310 or the atomizing chamber 6311 has a non-circular cross section, the aperture of the atomizing port 6310 or the aperture of the atomizing chamber 6311, respectively, is its equivalent diameter. The term "equivalent diameter" refers to the diameter of a circular hole having equal hydraulic radius as defined as the equivalent diameter of a non-circular hole.

Further, in some embodiments, the aperture of the atomizing port 6310 is in the range of 0.22mm to 0.35mm, the axial length of the atomizing chamber 6311 is in the range of 1.5mm to 3.0mm, and the aperture of the atomizing chamber 6311 is in the range of 0.7mm to 1.3mm, which can provide advantages in the manufacturing process of the liquid storage atomizing assembly 60.

The end of the liquid supply channel 620 that communicates with the atomizing chamber 6311 has a liquid inlet 6210, and the vertical distance between the center of the liquid inlet 6210 and the atomizing surface 6313 is critical to ensure liquid film formation. In some embodiments, the perpendicular distance between the inlet 6210 and the atomizing face 6313 may range from 0.3mm to 0.8mm, preferably from 0.35mm to 0.6mm.

Further, the atomizing channel 631 further includes an expanding channel 6312, and the expanding channel 6312 communicates with an end of the atomizing chamber 6311 remote from the air supply channel 632, and is configured to diffuse and spray liquid particles generated after atomization in the atomizing chamber 6311 in a jet manner, so as to increase a spray area of the liquid particles. The cross-sectional area of the expanding channel 6312 gradually increases from an end near the atomizing chamber 6311 to an end far from the atomizing chamber 6311. Specifically, in the present embodiment, the expanding channel 6312 is a conical channel extending in the longitudinal direction and having a pore diameter gradually increasing from bottom to top. The atomization angle of the expansion passage 6312 (i.e., the divergence angle of the expansion passage 6312) must have a proper range to ensure that the ejected liquid particles have a proper ejection range. Further, a streamlined, smooth connection, such as by being rounded, may also be employed between the expansion passage 6312 and the atomizing chamber 6311. In other embodiments, the expanding channel 6312 may have other shapes such as elliptical cone shape or pyramid shape.

The air supply channel 632 may in some embodiments include a converging channel 6321, the converging channel 6321 having a converging shape with a cross-sectional area that decreases from one end distal to the atomizing chamber 6311 to one end proximal to the atomizing chamber 6311 to enable the air flow from the air source 40 to be accelerated and ejected into the atomizing chamber 6311. In this embodiment, the constriction channel 6321 is a conical channel extending in a longitudinal direction and having a gradually decreasing aperture from bottom to top, and the aperture of the upper end of the constriction channel 6321 is smaller than the aperture of the atomizing chamber 6311, so that the junction between the constriction channel 6321 and the atomizing chamber 6311 forms a circular annular atomizing surface 6313. It will be appreciated that in other embodiments, the converging channel 6321 may be other converging shapes such as elliptical cone shape or pyramid shape.

The liquid supply channel 620 can be used to control the flow rate of the liquid supplied from the liquid storage cavity 610 to the atomization cavity 6311, so as to realize quantitative liquid supply from the atomization cavity 6311, and ensure that the flow rate of the liquid supplied to the atomization cavity 6311 reaches a design value. In general, the size of the fluid supply channel 620 may be matched to the flow requirements, i.e., the fluid supply channel 620 may create a resistance that matches the fluid supply force at the design flow. Specifically, the negative pressure generated in the atomizing chamber 6311 is hydraulic, and the hydraulic resistance includes the resistance along the liquid supply channel 620 and the negative pressure in the liquid storage chamber 610. The specific diameter and length of the feed channel 620 is designed by calculating the required on-way resistance of the feed channel 620 at the design flow.

In general, the greater the viscosity of the liquid matrix, the greater the resistance of the liquid matrix to flow through the liquid supply channel 620; the longer the extension path of the liquid supply channel 620, the greater the resistance within the liquid supply channel 620; the larger the cross-sectional area of the liquid supply channel 620, the smaller the resistance within the liquid supply channel 620; the more tortuous the fluid supply channel 620, the greater the resistance within the fluid supply channel 620.

Further, the supply passage 620 may include a main passage 622 and a feed passage 621, the main passage 622 being in communication with the liquid storage chamber 610, the feed passage 621 communicating the main passage 622 with the atomizing chamber 6311. The liquid inlet passage 621 may be a straight passage extending in a lateral direction, and its extending direction is perpendicular to the extending direction of the air flow passage 630. Further, the liquid inlet passage 621 may be a capillary passage. By designing the liquid inlet passage 621 as a capillary passage, when the air source 40 stops working and the negative pressure generated in the liquid supply passage 620 by the high-speed air flow disappears, the capillary force in the liquid inlet passage 621 can be utilized to reduce or avoid the backflow of the liquid matrix in the liquid inlet passage 621 to the liquid storage cavity 610, and the liquid supply delay in the next suction caused by the backflow of the liquid matrix in the liquid inlet passage 621 can be prevented.

In the present embodiment, the main passage 622 and the liquid inlet passage 621 are formed in the liquid storage assembly 61 and the nozzle 63, respectively. It will be appreciated that in other embodiments, the main passage 622 may also be formed partially in the reservoir assembly 61 and partially in the nozzle 63; alternatively, the liquid inlet passage 621 may be partially formed in the liquid storage unit 61 and partially formed in the nozzle 63.

The liquid storage cavity 610 is formed in the liquid storage assembly 61, the nozzle 63 is longitudinally penetrating through the liquid storage assembly 61, and both the liquid storage assembly 61 and the nozzle 63 can have a cylindrical shape. Further, the liquid storage assembly 61 may further be formed with a liquid filling channel 614 to fill the liquid storage cavity 610 with liquid again through the liquid filling channel 614 after the liquid matrix in the liquid storage cavity 610 is used up. In this embodiment, the filling channel 614 may extend longitudinally upward from the upper end of the reservoir 610. The reservoir atomization assembly 60 also may include a sealing plug 64 that removably plugs into the fluid injection channel 614. When priming is not required, the priming channel 614 can be sealed by the sealing plug 64 to prevent leakage of liquid matrix within the reservoir 610.

Specifically, in the present embodiment, the liquid storage assembly 61 may include a liquid storage main body 611, a liquid storage seat 612 embedded at the bottom of the liquid storage main body 611, and a sealing sleeve 613 sealingly disposed between the liquid storage main body 611 and the liquid storage seat 612. The liquid storage cavity 610 is formed in the liquid storage main body 611, and the liquid storage seat 612 is matched with the opening of the lower end of the liquid storage cavity 610 so as to cover the liquid storage cavity 610. In some embodiments, the liquid storage body 611 and the liquid storage seat 612 may be made of hard materials such as plastic. The sealing sleeve 613 may be made of an elastic material such as silica gel to improve its sealing performance.

Further, a receiving chamber 619 for receiving the vent pipe 80 may be formed in the liquid storage body 611. In the present embodiment, the central axes of the liquid storage cavity 610 and the accommodating cavity 619 are parallel to the central axis of the liquid storage assembly 61, and the inner wall surface of the liquid storage main body 611 only partially defines the liquid storage cavity 610, so that the cross section of the liquid storage cavity 610 has a substantially C-shaped structure, the accommodating cavity 619 is disposed on the side of the liquid storage main body 611, which is not defined with the liquid storage cavity 610, and the structural design can save the space of the liquid storage main body 611 in the lateral direction, so that the space is less. The nozzle 63 is located directly below the accommodating cavity 619 and is coaxially disposed with the accommodating cavity 619, i.e. the central axis of the nozzle 63 is parallel to the central axis of the liquid storage assembly 61.

The main passage 622 may be formed between the liquid storage body 611 and the liquid storage seat 612. Specifically, in the present embodiment, the lower end surface of the liquid storage body 611 is concavely formed with a liquid guiding groove 6111, and the liquid guiding groove 6111 may extend from a side wall of the liquid storage cavity 610 near the nozzle 63 in a direction toward the nozzle 63 in a lateral direction, which is a linear channel extending in the lateral direction in the present embodiment. The upper end face of the liquid storage seat 612 is a plane, after the liquid storage main body 611 and the liquid storage seat 612 are assembled together, the lower end face of the liquid storage main body 611 is attached to the upper end face of the liquid storage seat 612, and a main channel 622 is defined between the upper end face of the liquid storage seat 612 and the liquid guide groove 6111. The main channel 622 in this embodiment is formed by fitting the lower end surface of the liquid storage main body 611 with the upper end surface of the liquid storage seat 612, so that the main channel 622 can be designed into various shapes and sizes according to different resistance requirements, for example, various nonlinear shapes such as S-shape, square wave shape or fold line shape, the surface shape is easy to process and manufacture, and the dimensional accuracy is easy to control. In other embodiments, the lower end surface of the liquid storage body 611 may be a plane, and the liquid guiding groove 6111 is formed on the upper end surface of the liquid storage seat 612. In other embodiments, the main channel 622 may be formed between two other mating components, such as between the reservoir body 611 and the boot seal 613, or between the reservoir seat 612 and the boot seal 613.

Further, the liquid storage atomizing assembly 60 may further include a gas supplementing sleeve 68 sleeved on the lower portion of the liquid storage assembly 61. The air supply sleeve 68 is annular and is sealingly sleeved between the outer wall surface of the liquid storage body 611 and the inner wall surface of the casing 10. In some embodiments, the air-compensating sleeve 68 may be made of an elastic material such as silicone.

As shown in fig. 2-4 and fig. 6, an air supply channel 12 may be formed in the housing 10, and an air supply port 11 is further provided on a side wall of the housing 10, where the air supply port 11, the air supply channel 12, the output channel 81, and the air intake port 14 are sequentially connected. When the user sucks in the air inlet 14, the outside air can enter the air supply passage 12 from the air supply port 11 and be output to the air inlet 14. The air supply channel 12 can be used for the air supply function of the electronic atomization device 100, so that the electronic atomization device 100 can realize a combined air supply mode of active air supply of part of the air source 40 and suction of part of the users, and the sum of high-speed air flow provided by the air source 40 and air supplied through the air supply port 11 is the total air demand of the users. In addition, the air supplementing channel 12 can be used for matching with the conventional sucking action of a user, so that the user experience is improved, and meanwhile, the smooth outflow of the atomized aerosol can be further facilitated. Further, in the present embodiment, the air supply channel 12 and the air flow channel 630 are isolated from each other, so as to avoid the influence of each other.

Further, a ventilation channel 616 may be formed in the housing 10, and the ventilation channel 616 communicates the liquid storage cavity 610 with the outside for recovering the pressure in the liquid storage cavity 610, so as to solve the problem that the liquid supply cannot be stabilized due to the excessive negative pressure in the liquid storage cavity 610. During the pumping process, the liquid matrix in the liquid storage cavity 610 is reduced to bring about air pressure reduction, and the air exchange bubbles enter the liquid storage cavity 610 from the air exchange channel 616 when the air exchange negative pressure is reduced to the limit, so that the negative pressure of the liquid storage cavity 610 is restored. The air exchanging channel 616 cooperates with the negative pressure region of the atomizing channel 631 to provide an automatic stable supply of liquid to the atomizing channel 631. Typically, the negative pressure of the controllable reservoir 610 ranges from-200 Pa to-700 Pa.

A closed flow chamber 110 is defined between the upper end surface of the air supply sleeve 68, the outer wall surface of the liquid storage body 611, and the inner wall surface of the housing 10. The flow-through chamber 110 may be annular and a ventilation channel 616 may be in communication with the flow-through chamber 110. Further, ventilation ports (not shown) may be further formed on the wall of the ventilation chamber 110 to communicate the ventilation chamber 110 with the outside, so that the outside air can enter the ventilation chamber 110, and ventilation of the liquid storage chamber 610 is achieved through the ventilation channel 616.

In this embodiment, the ventilation channel 616 adopts a straight liquid ventilation structure, which may include a ventilation main channel 6120 formed between the outer wall surface of the reservoir 612 and the inner wall surface of the sealing sleeve 613.

The extension length of the air return groove 683 is smaller than the axial length of the air supplementing sleeve 68, so that the air return groove 683 is prevented from penetrating through the inner wall surface of the lower end of the air supplementing sleeve 68 longitudinally, and the air return groove 683 is ensured to be isolated from the gap cavity 671. The air supply grooves 682 and the air return grooves 683 are provided so as to be offset from each other in the circumferential direction of the air supply sleeve 68 and are not communicated with each other. It will be appreciated that in other embodiments, the air return groove 683 may be formed on the outer surface of the liquid storage body 611, or may be formed on both the outer surface of the liquid storage body 611 and the inner surface of the air make-up sleeve 68.

The ventilation main channel 6120 may further include an airflow channel 6124 that communicates the plurality of rotating channels 6121 and the plurality of communicating channels 6122 with the return air port 6112.

Further, the electronic atomizing device 100 may further include a heat generating member 83 disposed on the vent tube 80 in some embodiments. The heating element 83 may be provided on the outer surface or the inner surface of the ventilation pipe 80, or may be provided in the ventilation pipe 80. The heat generating element 83 is electrically connected to the power supply 30, and is capable of generating heat after being energized. The inner wall surface of the air-supplementing sleeve 68 may be further provided with a wire passing groove 684 through which the electrode leads of the heating element 83 pass, and the positive and negative poles of the heating element 83 are electrically connected with the power supply 30 through the two electrode leads, respectively. The structure and the heating form of the heating element 83 are not limited, and for example, it may be a structure of a heating net, a heating sheet, a heating wire, or a heating film, and the heating form may be a heating form of resistance conduction heating, infrared radiation heating, electromagnetic induction heating, or composite heating. In this embodiment, the heating element 83 is located above the nozzle 63, and the liquid particles sprayed from the nozzle 63 are sprayed upward into the output channel 81, and are evaporated and heated by the heating element 83 to generate aerosol, and the aerosol is then carried out of the output channel 81 by the airflow for the user to inhale or inhale.

Further, the liquid storage atomizing assembly 60 may further include a plurality of first electrode columns 6125 disposed on the liquid storage seat 612 along the longitudinal direction, and correspondingly, a plurality of second electrode columns are disposed on the bracket assembly 70 corresponding to the plurality of first electrode columns 6125 along the longitudinal direction. The first electrode column 6125 and the second electrode column are in contact and conduction with each other, so that the electric connection between the power supply 30 and the heating element 83 is realized.

In this embodiment, by adopting the manner that the nozzle 63 atomizes the continuously flowing liquid matrix into the liquid particles and then evaporates the liquid particles by the heating element 83, the surface area of the fine liquid particles formed after the nozzle 63 atomizes is greatly expanded, so that the heating and evaporation are easier, on one hand, the conversion efficiency of heat and aerosol can be improved, and on the other hand, the temperature of the evaporation process of the heating element 83 can be reduced, and the low-temperature atomization can be realized. At a lower heating atomization temperature, the liquid matrix mainly completes the physical change process, thereby solving the problem of thermal cracking deterioration of the liquid matrix caused by the atomization of the traditional porous ceramic or porous cotton in a high temperature mode, avoiding the phenomena of burning, carbon deposition, heavy metal volatilization and the like, keeping the special components of different liquid matrixes and essence and spice systems, and finally enabling an inhalator to feel the special taste corresponding to the original liquid matrix. In addition, the heating element 83 is not contacted with the liquid storage cavity 610, the heating element 83 is not soaked in the liquid matrix for a long time, and pollution of the heating element 83 to the liquid matrix is reduced, so that impurity gas in aerosol generated after atomization is reduced.

It will be appreciated that in other embodiments, the liquid particles ejected from the nozzle 63 may also impinge downwardly on the heat generating element 83, i.e. the heat generating element 83 may also be disposed below the nozzle 63; alternatively, the liquid particles ejected from the nozzle 63 may also impinge laterally on the heat generating element 83, i.e. the heat generating element 83 is at or substantially at the same level as the nozzle 63. In other embodiments, the electronic atomizing device 100 may not be provided with the heating element 83, that is, the liquid particles atomized by the nozzle 63 may be directly output through the output channel 81 and sucked or inhaled by the user.

Further, the electronic atomizing device 100 may further include a dust cap 90 detachably mounted on the upper end of the housing 10. When the electronic atomizing apparatus 100 is not required to be used, the dust cover 90 may be provided at the upper end of the housing 10 to prevent foreign substances such as dust from entering the output passage 81.

Figures 7-12 illustrate ventilation channels 616 in some alternatives of the present invention as alternatives to the straight flow ventilation channels 616 in the above-described embodiments. In the alternative illustrated in fig. 7-12, the forward flow of fluid in the ventilation channel 616 has a different flow resistance than the reverse flow, where the forward flow direction refers to the direction of fluid flow from the reservoir 610 to the ventilation channel 616 and the reverse flow direction refers to the direction of fluid flow from the ventilation channel 616 into the reservoir 610. The flow resistance of the fluid in the forward direction is greater than the flow resistance in the reverse direction in the ventilation channel 616, so that ventilation is smooth and the risk of leakage is reduced.

In a first alternative shown in fig. 7-9, the ventilation channel 616 comprises a main channel 6161 and a number of branch channels 6162 arranged on at least one side of the main channel 6161. The main channel 6161 is a linear channel having a first end 6163 in communication with the reservoir 610 and a second end 6164 disposed opposite the first end 6163. The branched channel 6162 is also a linear channel, one end of which communicates with the main channel 6161, and the other end extends in a direction away from the main channel 6161. Preferably, the plurality of branch channels 6162 are provided, and the plurality of branch channels 6162 can be symmetrically arranged at two opposite sides of the main channel 6161, so that the ventilation channel 616 is in a fishbone shape as a whole. The hydraulic diameters of the main channel 6161 and the branch channel 6162 can be between 0.1mm and 1 mm. The included angle θ between the two branch channels 6162 at the two symmetrical sides can be between 30 ° and 150 °.

As shown in fig. 8, when the liquid matrix flows forward from the liquid storage cavity 610 toward the second end 6164 of the main channel 6161, the liquid matrix fills the branch channels 6162 on the left and right sides under the wetting action of the solid wall surface due to the contact angle between the liquid and the solid wall surface of the channel, and then continues to flow toward the second end 6164 of the main channel 6161, so that the flow resistance of the liquid matrix in the ventilation channel 616 becomes large. As shown in fig. 9, when the liquid matrix flows in a reverse direction from the second end 6164 to the first end 6163 of the main channel 6161, the flow resistance of the liquid matrix in the ventilation channel 616 is reduced due to the coincidence of the solid wall surface wetting direction with the initial flow direction of the liquid matrix. By adopting the fishbone-shaped ventilation structure, when the liquid storage cavity 610 is ventilated, bubbles push the liquid matrix to reversely flow in the ventilation channel 616, the wetting direction of the solid wall surface is consistent with the initial flowing direction of the liquid matrix, and the liquid matrix is smoothly pushed back to the liquid storage cavity 610; after ventilation is finished, the liquid matrix positively flows in the ventilation channel 616, and the liquid matrix fills the branch channels 6162 at the left and right sides, and then continuously flows to the second end 6164 of the main channel 6161, so that the flow of the liquid matrix is delayed, and the leakage risk is reduced.

It will be appreciated that in other embodiments, the plurality of branch channels 6162 may be disposed on opposite sides of the main channel 6161 in a staggered manner, or the plurality of branch channels 6162 may be disposed on the same side of the main channel 6161.

In a second alternative shown in fig. 10-12, the ventilation channel 616 also includes a main channel 6161 and a number of branch channels 6162 disposed on at least one side of the main channel 6161. The main channel 6161 is a linear channel having a first end 6163 in communication with the reservoir 610 and a second end 6164 disposed opposite the first end 6163. Each of the branched channels 6162 is a continuous curved channel, and both ends thereof are communicated with the main channel 6161, so that the ventilation channel 616 is a tesla valve ventilation structure as a whole. Preferably, there are a plurality of branch channels 6162, and the plurality of branch channels 6162 may be disposed on opposite sides of the main channel 6161. The hydraulic diameters of the main channel 6161 and the branch channel 6162 can be between 0.1mm and 1 mm.

As shown in fig. 11, when the fluid flows in the forward direction from the liquid storage cavity 610 to the second end 6164 of the main channel 6161, the fluid direction of the branch channel 6162 and the fluid direction of the main channel 6161 are impacted due to the branching action of the branch channel 6162, so that the flowing resistance of the fluid in the ventilation channel 616 is increased, and the leakage risk is reduced. As shown in fig. 12, when fluid flows back from the second end 6164 of the main channel 6161 to the reservoir 610, the direction of the fluid in the branch channel 6162 is consistent with that of the main channel 6161, resulting in a substantial reduction of the flow resistance of the fluid in the ventilation channel 616, which is beneficial for the inflow of air bubbles into the reservoir 610.

It will be appreciated that the above technical features may be used in any combination without limitation.

The foregoing examples only illustrate preferred embodiments of the invention, which are described in more detail and are not to be construed as limiting the scope of the invention; it should be noted that, for a person skilled in the art, the above technical features can be freely combined, and several variations and modifications can be made without departing from the scope of the invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
